My guy asked me to cut a 1mm pitch thread on a custom shaft.

I could not do it on my lathe, so I finally bit the bullet and wrote a
subroutine to do threading with my 4th axis rotary table. I use a 60
degree chamfering end mill.

Now I can cut any thread, any pitch, right or left handed, and if the
thread is very coarse, the subroutine does it in several passes.

I am afraid that it does not create a 100% correct thread geometry,
but I hope that I can do enough things with it to be useful with some
adjustments to diameter.

Nice - to bad you can't use a hob ? I think that what thread cutters
are or Cob... They have cutters a foot long and 6" in diameter -
coated and all - here in Lufkin - the foundry at Lufkin Industries has
to do it all. Massive gears and massive bolts and nuts.

The traditional donkey that pumps out oil is twice as long as those made
by Lufkin. Their custom way saves space and when in buildings (hiding
the pump) it becomes important.

Yes, to do it properly, I would need to orient the rotary table at
angle to axis X. Too difficult for me to do it. I will mess with
making threads to see how geometry affects fit and how I can
compensate by fudging the diameter.

For a 1MM pitch, a hand ground, single point hss threading tool probably would have worked just as well and would also have produced the correct root geometry.

Converting a Bridgeport milling machine to Linux is also a skill.

And yapping on forums about "having access to a friend's shop" is not
a skill.

As for single point threading, my current problem is that the spindle
has to be on brake. However, spindle brake right now is tied to
estop. It only activates when the mill is e-stopped, and deactivates
when the mill is out of estop. Fixing that requires me to spend a
considerable time writing emc2 logic statements (to interlock brake
and estop and spindle running safely). I do not have time for this
right now.

Gaining skills means paying your dues. iggy refuses to pay his dues

kill filled Precision Machinist who, unlike Mark Wieber, refuses to
coddle and spoon feed iggy. The sad fact is that iggy can't handle
anyone who tells him the truth about his ****ed up approach to

prevented him from properly learning and acquiring the needed

Hey, Jon, knock it off. I saw what he did with his Bridgeport. This
guy looked deeply into what Bridgeport had done, and what was possible
with some modern components and his own programming skills, and did
something that would have amazed any of the commercial CNC retrofit
companies I've visited and interviewed.

Furthermore, he's gone from zero to a pretty good speed on learning
how to machine parts. He takes his own path -- he seems to be as
interested in the creative aspects of the work as in learning the
conventional wisdom. He's put a lot of work into it and he's tenacious
as hell.

He's paid his dues, but not to prepare for some conventional machining
job. He's doing his own thing and he's had some successes. Unlike many
others, he's more of an inventor than a follower, and he's not afraid
to fail.

That's not to knock conventional training. It's just different; much
rarer; and, to me, very interesting and impressive.

So lighten up on him. He catches some very unfair flak. I've never
seen him tell anyone that he knows how to do something, and they
don't. He's just doing it his way.

Wrong, Ed. iggy doesn't catch unfair flack. iggy is a hack, a butcher
and a jackass on an ego trip. For years iggy has refused to get basic
training for machining or welding and asks moronic question after
moronic question in this newsgroup expecting others to spoon feed him
because he won't pay his dues. When some refuse he insults them.
Recently he insulted Precision Machinst and insisted Precision
Machinist could not have a successful business.

I'm sick of iggy's bull****, his bragging constantly how cheaply he
purchased something for nothing, etc. iggy's email telling me the
prices I charge are too high because he's upset I won't sell him high
quality tools for pennies on the dollar is par for the course for this
****bag.

Your comments regarding the public's and potential buyers' perceptions of
the little black rifle were right on target, IMO.. for example.

I definitely noticed when you were gone, and was beginning to believe you'd
just moved on to something more worthwhile. I've seen it happen with so many

There are some very good forums such as Chaski where it's all-on-topic, all

You have a good point there, Bill. When I returned from vacation last
June and started to download posts from RCM, I stopped myself and
asked "why?" It was no fun, not very informative, and a waste of time.

So I just stayed away until I had a delay on a project this winter and
too much time on my hands. Devil's workshop, and all that. g

I think I'll just mosey along again after finishing my conversation
with RD. I don't want to cut him short again.

Thanks.

Converting a Bridgeport milling machine to Linux is also a skill.

As for single point threading, my current problem is that the spindle

estop. It only activates when the mill is e-stopped, and deactivates
when the mill is out of estop. Fixing that requires me to spend a

and estop and spindle running safely). I do not have time for this
right now.

iggy has very few metalworking or welding skills even after many years
of posting here. He's a butcher/hack with no clues.

Gaining skills means paying your dues. iggy refuses to pay his dues
and he has no respect for others such as Precision Machinist. iggy has
kill filled Precision Machinist who, unlike Mark Wieber, refuses to
coddle and spoon feed iggy. The sad fact is that iggy can't handle
anyone who tells him the truth about his ****ed up approach to
metalworking and welding. He's on a series ego trip that for years has
prevented him from properly learning and acquiring the needed
metalworking and welding skills and it shows in almost every post iggy
makes.

Hey, Jon, knock it off. I saw what he did with his Bridgeport. This
guy looked deeply into what Bridgeport had done, and what was possible
with some modern components and his own programming skills, and did
something that would have amazed any of the commercial CNC retrofit
companies I've visited and interviewed.

Furthermore, he's gone from zero to a pretty good speed on learning
how to machine parts. He takes his own path -- he seems to be as
interested in the creative aspects of the work as in learning the
conventional wisdom. He's put a lot of work into it and he's tenacious
as hell.

He's paid his dues, but not to prepare for some conventional machining
job. He's doing his own thing and he's had some successes. Unlike many
others, he's more of an inventor than a follower, and he's not afraid
to fail.

That's not to knock conventional training. It's just different; much
rarer; and, to me, very interesting and impressive.

So lighten up on him. He catches some very unfair flak. I've never
seen him tell anyone that he knows how to do something, and they
don't. He's just doing it his way.

Yeah Ed, I appreciate a lot of the encouragement that I see. I mean I
come in here mainly for the electrical/plumbing/HVAC aspect, but
still... You now, this back and forth with the insults almost takes
on a comedy at the improv aspect, and some of the people here just
can't seem to shake rivalries caused by insults in previous posts.
But sadly, I honestly don't think it will do any good telling anyone
here to act like grown-ups, but then again, I understand somebody's
got to at least try.

Thanks, Ed. As of now, this Bridgeport has three major enhancements
that I added, that improved on what it could do originaly.

1. Spindle encoder lets me do rigid tapping. I have a small lathe
chuck that can be mounted in the spindle, and I hope one day to work a
bit on making this work as a poor man's CNC lathe.

2. 4th axis based on a rotary table. It uses a resolver instead of
more modern encoders, but fortunately Jon Elson had a nice resolver to
encoder converter board.

3. The knee is fully motorized with a servo motor, making it an
additional "axis" and enhancing my work envelope. I have not, as of
yet, added home and limit switches, so it is not as safe as it should
be.

Before I go, there's something I've wanted to leave here that I think
some machining hobbyists can make use of. I met Dick Moore and
interviewed his son Wayne, and Dick's work and writing was a huge
influence on my hobby interest. He wrote a book in 1955, _Holes,
Contours and Surfaces_, which explains how extraordianry accuracy was
achieved before CNC and all of the closed-loop compensation we have
today. I'll post a link to it below.

Moore's son Wayne is famous for _The Foundations of Mechanical
Accuracy_ (1970). It's also a great book and is available in reprint.
The first book is about how the work is done; the Foundations is about
how Moore built the machines that lifted us out of the very early era
into the pre-CNC Jig Borer and Jig Grinder era. It's worth seeing just
for the outstanding photography. LIFE magazine had just collapsed and
Moore got one of their laid-off photographers. The work shows how
black & white photography can be done, and it beautifully illustrates
many of Moore's principles, including his insightful work on
self-checking gages and making ultra-accurate leadscrews. I used to
watch his scrapers achieve 20 microinch flatness, corner-to-corner, on
the Moore measuring machines. It was amazing.

That's my interest in this hobby, particularly in how things were done
in toolmaking and gage-making before Moore. I've read three of his
earlier books that aren't even listed in the Library of Congress,
probably because Moore Special Tool self-published them. They may be
gone but we had them at McGraw-Hill's library several decades ago. One
was on the design and operation of the jig borer; a second on the jig
grinder; and the third was a predecessor to the book linked below,
_Precision Hole Location_ (1946)

This is not like the old Colvin and Stanley books, which were about
general machining. This is about the bleeding edge of accuracy. And
keep in mind that most tooling work before CNC was drill jigs. The
extreme examples -- master jigs for clock and watch plates -- required
+/- 50 microinch accuracy. They could do it in 1920 but it was very
slow (I have three custom faceplates and two sets of toolmaker's
buttons, which were used for that work). When Moore got involved in
the 1930s, the focus switched to making machine tools that would do it
on an every-day basis, and to machining contours to the same degree of
accuracy:

The only people that would listen to a "heads up" from you have zero
ability to reason and think for themselves... much like Wieber's

You going off on EA for telling you the truth about the Chevy Volt and

KiddingNoOne doesn't keep anyone in line and his logic and reasoning
are often badly flawed. Bragging about his Chevy Volt and his
inability to understand what's so wrong with the Chevy Volt shows just
how far KiddingNoOne has his head shoved up his ass. In addition,
KiddingNoOne isn't able to comprehend the real problem with his
approach to Mark Wieber. It's Mark Wieber's cult of idiots (of which
iggy is most certainly a member) that are the real problem not Wieber
himself.

If you truly cared about this newsgroup or in increasing your
metalworking related skills, Ed you wouldn't spend the massive about
of time you spend debating with Wieber on off topic subjects where
Weiber has proved for many years he won't tolerate others who have
different political views than he does.

Wrong again, iggy.

What kill files amount to in your case are the only way you can deal
with those in this newsgroup who refuse to spoon feed you and coddle
you. Your kill file allows you to not have to deal with those who call
you out on your frequent false claims, your ridiculous naivety and
your refusal to pay your metalworking and welding dues. Kill files are
for pussies and you most certainly are one just like your hero Mark
Wieber.

An example of one of your false claims is you comparing your actions
to what Aaron Swartz did. That you attempted to compare yourself to
Aaron Swartz shows how ****ed in the head you truly are. So does your
constant bragging about how cheap you buy stuff. The later shows where
you place the majority of your focus rather than working on really
building metalworking or welding skills.

Banquer, metalworking isn't his livelihood! He makes his living "buying

How can you fault a person for not developing skills they don't use

When he _has_ a metalworking question, he comes here and asks. Isn't

But he's not TRYING to be a 'decent machinist'. I'm not even sure that's
in his top twenty priorities. He's a used equipment dealer, earning a
